My first instinct would be Makey Makey as well, but my second would be to use the guts of a wired mouse and make a button that completes the circuit for the left-click (potentially even remapping the mouse click on the computer to an actual keyboard key so you don't need an Isadora Control Panel with the mouse over a button to trigger whatever it is that you want to trigger).

Hello folks,
What do you think would be the simplest, cheapest, easiest and most reliable way of adding a physical button to an Isadora system for a kind of kiosk installation? A momentary signal from a push button would be perfect for things like resetting, or capturing a JPG of the stage.
I have a couple of wooden boxes that house MIDI controllers, each with custom buttons that poke switches or keys on the controllers, but these are a bit of a waste of space.
Something like a Makey Makey Go in a custom box might be nice, but it's difficult to get hold of the boards these days.
How easy is it to dismantle an old keyboard and build a single-key case, then have it USB'd into Isadora and use a keyboard watcher? (this would be in addition to the main keyboard)
I guess Arduino would be an option, but that requires a bit of programming. Could anybody recommend a good, cheap board for this?

I would love a Value Delay that has a time input. So you could specify how long you want the changes in values to delay for. I made one once that really was too complicated, involving 2 values that control the x and y of a small dot generated in a Shapes actor, the resulting video is fed through a Video Delay into an Eyes, which outputs the 2 values as x and y of the dot. It worked ok, but was quite resource-heavy. I wonder if Python could achieve a similar result?

I've added delay to data before in this situation using the Data Array actor.

I have an arduino mega that's connected to two stepper motors.  Each stepper motor has one stop/limit switch that would indicate the end of the travel distance.  I'm using "AccelStepper" library to control the motors.  I'm also using the "Eventually" event-based lib to do perform some action when an event occurs. 

Everything works great in serial fashion. But I need to have a few things run at the same time. The two stepper motors, for example. The issue that I have is AccelStepper is blocking meaning that once I call "runToPosition" function call, nothing else happens unless and until the function returns.  

I looked at "Metro" and "Chrono" packages but again since the "runToPosition" is a blocking function call, everything comes to the halt until the function call returns.

Of course, one thing I can do is move each motor a few degrees in a loop with AccelStepper lib or just pulsing it.  But I was wondering if there is any stepper motor libs that are asynchronous?  Something like fire-and-forget.  Thanks all.

Thanks both - that will do it. Cheers.

Funny isn't it - sometimes the simple ones catch you out.

Thank you for your tips, I've tried but something failed, sure I did something wrong !

Your tips seem the good way to have what I need.


But to explain better, here is the live dispositif into the museum for this scene (we are filming the yellow round on the wall)

Yes, the NDI HX camera is great.

Also EpocCam works well. But I prefer the NDIHX.

Hi,

I’m looking in to getting a live video stream from my iPhone to Isadora. Which iPhone app works best for that? Preferably a one time purchase, no subscriptions based apps. is NDI the way to go?
